Did it work effectively? What's your percentage vision restoration like?

I would say so, 10 years on and I am still able to see without optical aid, although my vision in the left eye is gradually deteriorating but far less than when I was wearing glasses/contact lenses. Money well spent (especially now its a 1/4 of the price it was 10 years ago) as I used to have galsses for ordinary wear (replace every other year), contacts (replaced every year) for sport use and an optical diving mask (only had one made up) for scuba diving.

Most glasses lenses are made out of polycarbonates (for lightness, cost savings and for safety reasons) and therefore dont generally shatter even when struck really hard.

Really?

Well, if you say so. It's not a subject I'm knowledgable about.

But if I were to wear glasses for badminton, I'd want to make damn sure they wouldn't shatter. I wouldn't just assume that it will be okay. I know of people who've had eye injuries from shattered glasses.

i use spectacles. bottom of the lens chipped by my racket while defending from a drive to my face. but my specs have saved me once when i was still a beginner......i might've become blind already if it wasn't for it lol

Actually no, some lenses are made out of pollycarb others are made out of glass, orthers out of alternative plastic. If your playing sport and wearing glasses folks choose polycarb lenses as they dont usually shatter. OK they may cost you a few $ extra but its money well spent as there lighter too.

My specs saved me a number of occassions. A few times from fast smashes. Once, from being wacked by a racket. The contact with with the racket made me flinch and save both my specs and eyes.

Other people have not been so fortunate. A contact lense wearer was shot in the eye and had to go to hospital. A woman was shot in the eye and cried. Another guy got wacked by his partner's racket. It looked horrible, but he didn't go to the hospital.

Must be glass. Plastic do not shatter. Be sure. It can be cracked although but with no small particles. I once tried to shtter my old glasses (moved to stronger lences) with a hammer and the power I needed to crack them could easily shatter the scull as well. 8) Never after that I was worried about wearing plastic glasses during play...

There was this Oakley ad some time back that showed their blade lenses staying intact after being shot by a shotgun. So we tried the same thing at the gun range with an old pair of scratched up blade lenses and #8 birdshot at 15 yards. The lenses where cracked up where the pellets got imbedded in the lens, but no pellets got thru and the lenses stayed intact. This is one reason Oakleys are very popular in the shooting sports.
